Using Regression Testing to meet Industry Requirements
Sourabh Bhambri Global Engagement Manager | December 1, 2016

Present day Industry & its complexities

In the present era of extremely fast changing technologies, it becomes necessary to be up to date. The demand of the present moment is to keep pace with the fast moving world by using latest technologies before they turn obsolete by another newer one. Updates, upgrades, and the introduction of new devices or services is a normal phenomenon of the present hour.

In the connected world in which we live, every second matters. Thus, there is a huge responsibility on the industries not only to ensure 24X7 service around the globe but also have a high efficiency and effectiveness.

Regression is a tool that helps the industries cope up with various challenges.

Why is regression testing required?

In regression testing, a number of test cases are kept running, so as to ensure that the product or service doesn’t break due to changes in the functional code arising out of an upgrade or new product/feature introduction.

Thereby, regression testing ensures best customer experience and continuous functioning.


With several phases between the testing and its execution, regression saves a lot of time, money, resources, and effort (both human and machine).

Regression is introduced at the test design phase as well as the execution phase. To test the product whether it meets its desired specifications or not, can be tested using regression.

Also, from an industry perspective, testing is required, as the introduction of any new device or an upgrade may lead to loss of functionality of a previously working setup.

To ensure continuity of the technological setup, its devices, and services, it is essential to run several test cases in a controlled environment and predict how to position the upgrade or new product along with associated codes.

With changes in a functional code, the chances for bugs to creep in arises. Thus, a functional code which was working as expected earlier may misbehave and not deliver on the expected functionality.
If this bug manages to find its way to the end customer, it may hamper the full experience which the product’s maker might have envisioned.

This is where regression comes into play.

What are the Challenges faced?

The present day challenges faced across the industries include low regression bug yield, longer cycle time and inadequate capacity to support regression needs, late detection of bugs during later part of regression cycle, automated scripts and hardware inventory maintenance, test coverage, and automation gap, results in customer found regression defects (CFR), and increase in Capex and Opex due to redundant investment on hardware and test infrastructures - Static Topologies & Tools

How is HCL leading in the Regression Space?

HCL has been a pioneer in the regression space.

HCL is the world’s 1st organization assessed for CMMi L5 (Dev & Services + SSD) V1.3. Also, HCL is India’s 1st software services company to get certified for ISO 13485.

Our differentiators include various certifications in the regression space, several frameworks to ensure that the right kind of regression service is being offered to your organisation to meet the specific needs and specifications.

Since the last few decades, HCL has served several companies of various sectors, ensuring huge value creation for the client, successful handling of several projects, successful product launches, and very high customer satisfaction score from the feedback surveys. HCL, with several patents approved and many more in the line, is the perfect choice for getting your regression solution.
